FIG. 2 is a diagram showing a display on the liquid crystal display 240 of the display section 24. As shown in FIG. Here, a state is shown in which all display elements are turned on, and in reality, they are selectively displayed. That is, the liquid crystal display 240 displays the file lock (rewrite prohibited) display 24.
1, recording mode 242, remaining battery level display 243, folder display 244, first to fourth character string display sections 245 to 24
8 and the like. The first to fourth character string display portions 245 to 248 are portions where numbers or characters are displayed.

FIG. 3 is a diagram showing a main flowchart of the present audio recording / reproducing apparatus.

That is, the operation starts when power is supplied to the circuit by loading a battery or the like.
Initial settings such as various parameter settings and hardware reset are performed (step S11).

Next, the encoded audio data is
The memory card 18 recorded as an SS file
It is determined whether or not the memory card 18 is loaded in the main body of the audio recording / reproducing apparatus (step S12). If the memory card 18 is not loaded, the process waits until the memory card 18 is loaded. Here, in this audio recording / reproducing apparatus, normal operation cannot be performed when the memory card 18 is not loaded. Therefore, when the memory card 18 is not loaded, it is further determined whether or not any operation switch is operated (step S13).
If the operation is not performed, the process returns to step S12. If the operation is performed, a warning is displayed on the display unit 24 indicating that the memory card 18 is not loaded and the operation cannot be performed.
After a warning sound is emitted from the speaker 21 to notify the user (step S14), the process returns to step S12.

On the other hand, if the memory card 18 is loaded, the currently selected folder is determined according to the folder selection information recorded in the internal memory 28 (step S15). If any of the folders A, B, or C has been selected, the normal mode is set, and the process proceeds to the normal folder process for the selected folder as described later (step S16). In addition,
If nothing is specified as the folder selection information, the folder A is set as the initial setting.

If all the folders have been selected, the mode is set to the ALL folder mode, and the process proceeds to the ALL folder process described later in detail (step S17).

In the initial setting, the default parameters stored in the built-in memory 28 are stored on the basis of the setting information of the sort item recorded on the memory card 18 or if they are not set yet. (For example, in order of recording date and time and in ascending order), all the DSS files stored in the memory card 18 are sorted, and the result is stored in the reproduction order table. This eliminates the need for the rearrangement process when shifting to the ALL folder process, so that the process can immediately shift to the ALL folder process, that is, folder switching can be performed smoothly.

Here, the rearrangement processing will be described with reference to FIGS.

For example, FIG.
8 is a diagram showing the attributes of files recorded in FIG.
Thus, a plurality of DSS files are stored in folders A, B, and C.
When the setting information of the sort item is “recording date and time and in ascending order”, the sorting is performed based on the setting information, and the reproduction order table 18A stores in FIG.
Is recorded as shown in FIG.

That is, in the reproduction order table 18A, information on the reproduction order, the file name (information for specifying the file), and the sort order (setting information of the sort item) are recorded. At this time, the contents of the field used for sorting are not recorded.

FIG. 4B shows an example in which the data is sorted by “recording date and time and in ascending order”. For example, if the data is sorted by “file capacity and ascending order”, the DSS file “A4.dss” is obtained. Is a desired file, it can be found immediately, and "user ID and ascending order"
If the DSS file "B1.dss" is a desired file, it can be found immediately.

FIG. 5 is a diagram showing a flowchart of the normal folder process executed in step S16.

That is, first, the RECSW 26D is turned on.
It is determined whether or not it has been performed (step S21), and it is turned on.
If so, a recording process is executed (step S22).
In this recording process, the DSS file is recorded in the current folder according to the information of the current folder (the folder where the current folder is) recorded in the internal memory 28. At this time, the file name of the recorded DSS file is added to the end of the table data of the reproduction order data file in the current folder. Then, the recording process is terminated by the operation of the STOPSW 26F. At this time, the above-described rearrangement process is performed, and the process of updating the reproduction order table 18A used in the ALL folder process is also performed. It is. If the reproduction order table 18A is not updated as described above, reproduction data of a newly recorded DSS file will not be created, and reproduction in the ALL folder mode will not be possible. Alternatively, the rearrangement process must be performed when the mode shifts to the ALL folder mode.

When the RECSW 26D is not turned on, or after the recording process is completed, the PLAYSW 26D
It is determined whether or not 26E has been turned on (step S2).
3) If it is turned on, a reproduction process is executed to start reproduction of the currently selected file (current file) (step S24).

FIG. 6A shows a display state of the liquid crystal display 240 during the normal reproduction. That is,
A recording mode display 242 is performed according to the recording mode of the current file, and a folder display 244 is performed according to the current folder. Then, the total number of files in the current folder is displayed on the second character string display section 246, and the current number indicating the reproduction order of the DSS file in the current folder is displayed on the first character string display section 245. Is displayed. The third character string display unit 247 displays the time of the current playback position in the current file, and the fourth character string display unit 248 displays the file length of the current file as time display. Displayed with column (LENGTH).

If the PLAYSW 26E is not turned on, or after the end of the reproducing process, the FFSW2
It is determined whether or not 6G is turned on (step S25),
If it is turned on, skip to the next file in the current file (step S26). F above
When the FSW 26G is continuously pressed, the skipping ratio is sequentially increased. In addition, skip cannot be performed for different folders.

If the FFSW 26G has not been turned on, or after the skip to the next file has been completed, it is determined whether or not the REWSW 26H has been turned on (step S27). (Step S2)
8). Others are the same as the case of the above-mentioned FFSW26G.

If the REWSW 26H has not been turned on, or after the skip to the previous file has been completed, it is determined whether or not the ERASESW 26J has been turned on (step S29). (Step S30). This erasing process is a process for erasing the current file from the memory card 18. In addition to erasing the file entity, at the same time, information on the erased file is obtained from the reproduction order data file and the reproduction order table 18A of the current folder. Is to be deleted.

When the ERASESW 26J is not turned on or after the erasing process is completed, the MENU
It is determined whether or not the SW 26I has been turned on (step S3).
1) If it is turned on, menu setting processing is performed (step S32). In this menu setting process, parameters can be set for the following setting items.

Recording mode (SP / LP) Operation sound (ON / OFF) Alarm (time / ON / OFF) File lock (ON / OFF) Display folder name (up to 8 characters for each folder) User ID (Up to 16 characters) ・ Clock setting When selecting parameters or setting items, use the FF
The SW26G is used as a + button, the REWSWH is used as a-button, and the PLAYSW26E is used as a confirm button.

If the MENU SW 26I is not turned on, or after the menu setting processing is completed, the U
It is determined whether or not the SB connection terminal 29 is connected to a PC (not shown) (step S33). Here, if it is determined that the PC is connected, a communication process is performed (step S
34). By this communication processing, the PC can change the user ID, change various settings, and transfer files. Basically, the operation from the audio recording / reproducing apparatus cannot be performed during communication, that is, the input of the operation switch group 26 is invalid. Then, when the communication state with the PC is released, the communication processing is terminated.

Thereafter, it is determined whether or not rearrangement is necessary (step S35). That is, the DSS file is deleted by the communication with the PC or the DS
If the S file has been transferred, the D
The number of SS files increases or decreases, or the order of DSS files is changed. So, in such a case,
A rearrangement process is performed based on the setting information of the sort item (step S36).

Also, for example, a user ID, an editing date and time, etc.
Similarly, when there is a possibility that the arrangement order at the time of displaying the ALL folder may be changed due to rewriting of file information or the like, the rearrangement process is performed.

Then, when it is not connected to the PC, or when the rearrangement is not necessary as a result of the communication process, or after the rearrangement process is performed, the FLSW2
It is determined whether or not 6K is turned on (step S37),
If it is not turned on, the process returns to step S21. On the other hand, if the FLSW 26K is turned on, a folder switching process is performed (step S3).
8) Return to the main flowchart. In this folder switching process, each time the FLSW 26K is turned on, the folder is switched cyclically in the order of A → B → C → ALL → A →. The information of the switched selected folder (current folder) is stored in the built-in memory 28, and can be retained even when power is not supplied.

Next, the ALL folder process executed in step S17 will be described with reference to the flowchart shown in FIG.

That is, first, the RECSW 26D is turned on.
It is determined whether or not it has been performed (step S41), and it is turned on.
If so, a warning is issued (step S42). That is, in the ALL folder mode (ALL folder processing),
Since no specific one folder is selected, recording cannot be performed, and when the RECSW 26D is turned on, a warning is issued to notify the user that recording cannot be performed. However, for example, in the ALL folder mode, the recording process may be performed by preliminarily determining that recording is to be performed in the folder A.

If the RECSW 26D has not been turned on, or after the warning, it is determined whether or not the PLAYSW 26E has been turned on (step S43). Is started (step S44).

FIG. 6B shows the display state of the display section 24 during reproduction in the ALL folder mode. That is, the recording mode display 242 is performed according to the recording mode of the current file, and all folders are displayed as the folder display 244 to indicate the ALL folder mode. Then, the total number of files of all folders is displayed on the second character string display section 246, and the first character string display section 245 indicates which folder and which reproduction order DSS file the current file is. The number and the number indicating the number of the current file among all the rearranged files are alternately displayed at predetermined time intervals (for example, 2 seconds). That is,
For example, “B95 / 289” and “1/289”
Are alternately displayed. The third character string display section 247 displays the current playback position in the current file in time, and the fourth character string display section 248 displays a sort key (sort item setting information). , And information on the field that is the sort key.

When the PLAYSW 26E is not turned on, or after the end of the reproducing process, the FFSW2
It is determined whether or not 6G is turned on (step S45),
If it is turned on, the selected file (current file) is skipped to the next file in the sorted order recorded in the reproduction order table 18A (step S26). When the FFSW 26G is continuously pressed, the skipping ratio is sequentially increased.

If the FFSW 26G has not been turned on, or after the skip to the next file has been completed, it is determined whether or not the REWSW 26H has been turned on (step S47). According to the sorted order recorded in the table 18A, the selected file (current file) is skipped to the previous file (step S48). Others
This is the same as in the case of the FFSW26G.

If the REWSW 26H has not been turned on, or after the skip to the previous file has been completed, it is determined whether or not the ERASESW 26J has been turned on (step S49). (Step S50). This erasing process is a process for erasing the current file from the memory card 18. In addition to erasing the file entity, at the same time, the reproduction order data file of the folder storing the file and the reproduction order table 18A are stored. , The information about the deleted file is also deleted.

When the ERASESW 26J is not turned on, or after the erasing process is completed, the MENU
It is determined whether or not the SW 26I has been turned on (step S5).
1) If it is turned on, first, the sort items are set (step S52). That is, in the ALL folder mode, the MENU SW 26I serves as a sort item setting button (normal menu setting may be performed, but the number of items increases, the processing becomes complicated, and the operation becomes complicated).

In this sort item setting, first, one of the following items is selected.

The order of recording date and time. The order of file size. The order of file name. The order of user ID. Then, one of ascending order and descending order is selected. The button operation is the same as in the menu setting process in the normal folder process.

After the setting is completed, next,
A rearrangement process (sort process) is performed (step S5)
3). The result of this rearrangement processing is shown in the reproduction order table 1
8A is recorded in the memory card 18. At the time of the next sorting process, referring to the key information (setting information of the sort item) in the playback order table 18A, if a different sort item is set, after the sorting process, the playback order is changed. Table 18A is overwritten.

When the MENU SW 26I is not turned on, or after the rearrangement process is completed, the FLS
It is determined whether or not W26K has been turned on (step S5).
4) If it is not turned on, go to step S
Return to 41. On the other hand, FLSW26K is ON
If so, a folder switching process is performed (step S55), and the process returns to the main flowchart. In this folder switching process, the FLSW 26K is
Every time N is performed, the folder is cyclically switched in the order of ALL → A → B → C → ALL → A. The information of the switched selected folder is stored in the built-in memory 28, and can be retained even when power is not supplied.

[Second Embodiment] In the first embodiment, immediately after shifting to the ALL folder process, the rearrangement process is not performed in consideration of smooth folder switching. Therefore, the sorting process is performed at the end of the recording process of the normal folder process, and therefore, a slight waiting time occurs at the end of the recording.

As one of the methods for solving this, the second
In the embodiment, the sorting process is not performed at the end of the recording process, and the memory card 18
The rearrangement process is executed once based on the setting information of the sort item in the box. Then, the above step S55
By executing a folder switching process 2 as shown in FIG. 4C in place of the folder switching process in FIG.
What is necessary is just to avoid shifting to the L folder mode.

That is, it is determined whether or not the FLSW 26K is ON for 0.5 seconds or more (step S61).
If the switch is ON for 0.5 second or longer, the mode shifts to the ALL folder mode (step S62). On the contrary,
If the FLSW 26K has not been turned on for 0.5 seconds or longer, the folder A is selected when the currently selected folder is the ALL folder, the folder B is selected when the folder is the folder A, and the folder B is selected when the folder is the folder A. Is folder C
In the case of folder C, the selected folder is set in folder A.

In this way, the folders A, B, and C can be switched smoothly without resorting to the ALL folder mode because of the absence of the ALL folder mode.
Also, the rearrangement process can be performed only when shifting to the ALL folder mode, that is, only when necessary.

[Third Embodiment] In the first and second embodiments, all files stored in all folders can be referenced (and selected) in the ALL folder mode. It can be considered that only files stored in a plurality of desired folders can be referred to.

In this case, a process called folder selection may be added before the sort item setting process in step S52.

That is, in this “folder selection” process, the folder display 244 of the display section 24 blinks sequentially from “A”, and at the same time, “ON” or “OFF” is displayed on the first character string display section 245. Is made. Then, the FFSW26G / REWSW26H is operated by a user.
Is changed according to the ON of the PLAYSW26E.
Is set to ON, "B" is displayed as the folder display 244.
Blinks and moves to the setting of the next folder, and so on.

Thus, after the folder desired by the user is selected, only the selected folders are lit in the ALL folder mode as the folder display 244, and all the files displayed on the second character string display section 246 are displayed. As for the number, the total number of files in the selected folder is displayed.

Although the present invention has been described based on the above embodiments, the present invention is not limited to the above embodiments, and various modifications and applications are possible within the scope of the present invention. Of course.

[0084]

As described in detail above, according to the present invention,
Even when a plurality of folders are provided, it is possible to provide a data reproducing apparatus capable of quickly finding target data.
